|I've never seen any of the Saw movies, but I know from my rampant TV-watching that the 6th one is out now. Six movies, apparently all with the same characters and plot? When can we move on to something new?
To be fair, TV shows do the same thing. The Simpsons has been on the air for two decades. Sure, there's some plot variation and character development, but it's essentially the exact same thing week after week for something like 400 weeks. But we know that going in. We know each episode is part of a larger story and doesn't necessarily stand on its own. Movie sequels are sometimes a surprise because the original seemed to end perfectly fine. And at some point, a sequel is simply a money-grab, using the name of the original success to generate more income with less effort. Pirates of the Caribbean comes to mind.
I played a video game recently called Far Cry 2, which would suggest it was a continuation of Far Cry, but which Wikipedia says "has very few noticeable similarities to the original game ... [and instead] features completely new characters and setting, as well as a new style of gameplay..." In other words, it's a completely different game, made to seem similar by using the same name. #entertainment
